Check Operation
Operation of the high limit thermostat must be
checked regularly. Use the following procedure:
a) Remove the electrical cabinet top panel assembly and
side panel as described in Paragraph 3.2.
b) Fill the pan with unused oil to the indicated mark
(50mm maximum). Place a thermocouple or
thermometer 25 mm below the oil surface in the
middle of the pan.
WARNING
DO NOT OVERFILL WITH OIL OR
FIRE MAY RESULT!
c) Ensure that the electrical power is off before
continuing. Bypass the operating thermostat by
placing a jumper across the terminals. This
effectively removes the operating thermostat
from the circuit.
d) Switch the unit back on and heat the unit as
described in the heating instructions, above.
The elements will heat up the pan.
CAUTION
DO NOT LEAVE THE APPLIANCE DURING THIS
TEST.
e) If the high limit thermostat is functioning
correctly, the elements will cut off as the
temperature reaches 205 to 230ºC. Once the
high limit thermostat has tripped, switch off the
mains electricity. Remove the jumper from the
operating thermostat and replace all panels.
f) If the high limit thermostat switches, but not at
the specified temperature, the thermostat
requires replacement. Rejected thermostats
must be logged and returned.
g) To remove, see replacement procedures above.
h) Replace covers removed in step “a.”
NOTE:
After this test, remove the jumper from
the operating thermostat.
